500 allows the cheese to barely pass this kata. Perhaps go to 1000 tests?

Can be cheesed in Python.

Finite decimal representation (except for recurring digits) => only rational.

Are the decimal numbers rational numbers or can they be irrational, transcendental?

[Python]

• updated to new test framework
• number of tests reduced from 6075 to 500

IMHO '0/1' is better than '-0/1'.

Why keep an useless '-' when all other things are simplified?
For example: '0.2'->'1/5' ('2/10'); '00'->'0/1' ('00/1'); '00.00'->'0/1' ('0/100' or '0000/100')

There's also this one, which does overlap - but not for the original language ( Rust ).

The three languages of this one and the two of the other have a total overlap of zero.

I wouldn't know what to do in this situation.

Good work! One small oddity: for inputs like "-0", the function cannot return "-0/1"; it must remove the negative sign. I'm not sure if that was intended. You might want to clarify in the description, or allow "-0/1", or completely remove any test cases with "-0".

Good kata!
I like these math problems ;)
